CARPET-BEATING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 276,494, dated April 24, 1883.

Application filed December 9, 1882. (No model.)

To all whom it may concern:

Be it known that I, JOHN SPAULDING, a citizen ot'the United States, residing at San Francisco, in the county of San Francisco and State ofGalifornia, have invented a new and useful Carpet-Beating Machine, of which the following is a specification.

' My invention consists essentially of a series of carpet carrying and feeding rollers, of a flexible adjustable bed upon which the carpet is held while being struck, and of thefiexible'beaters attached to a rotating shaft; and it furthermore consistsin the peculiar construction and arrangement of the said rollers, supheaters. These several objects accompanying drawings, in which-- rollers of the carpet-table.

porting-bed, and heaters, and the mechanism for operating the same.

The objects of my invention are, first, to provide a continuous feeding and discharging carpet-beating machine with an elasticinterspaced bed or platform upon-which the carpet receives the blows of the heaters as it is fed forward or backward; second, to provide a carpet beatin g or cleaning machine with a sectional beater-bed, the various sections of which are adapted to be raised or lowered, eitherindependently or collectively, so as to form a bed of varying length to'accommodate carpets of different breadths, and to provide means whereby such portions of the beater-bed not in actual use may be lowered or drawn back and out of reach of the I accomplish by means of the mechanism illustrated in the Figure l is a vertical cross-section through onesection of my improved carpet-beatin g ma elrs. Fig. 3 is a section taken on line as a: of Fig. 2. Fig. 4 is a bottom view of the carpetsupportiug table or bed, and Fig. 5 is a longitudinal sectional view of the same. Fig. 6 is an enlarged front view of the upper carrying- Fig. 7 is a top view.

Similar letters of reference are used to des i gnate like parts throughout the several views.

A and B represent two carpet carrying or feed rollers, which are journaled in fixed bearings, and the one marked B is placed to the rear, and somewhat above the axial line of the roller A. These feed-rollefs may be either plain-surfaced or provided with shallow circumferential grooves, and'over them is passed the carpet-feed belts or bands 0, which may I be of any suitable width, and are placed at suitable intervals apart, the spaces between such belts being occupied by the metal tongues D, which are bolted to the cross-timber E, and serve as guides to direct the-carpet upon the beater-bed.

I-n-order that the carpet may be pressed tightly upon the feed belts and rollers, I proupon a shaft, G, which can be raised and lowered at pleasure by means of the suspending-chain H and lever-arm I, pivoted to the frame-work of the machine. The vertical alignment of the shaft G is secured and lateral movement is prevented by means ot' the channeled guide-posts J. The beatenbed is supported by the curved rods K, the upper ends of which form a bearing for the shaft or axle L, which carries the friction rollers or pulleys M, and the lower end carries the small grooved wheels N, which roll upon the track 0 as the beater-bed is raised or lowered. The upper endof each rod is connected by means of a chain, P, to the web Q of the guide-tongues I), and the lower end of each rodis provided with a chain, R, which passes over a pulley, S, placed tothe rearot'the rod, and is then brought forward and attached to the combined chain and ratchet wheel T, loosely hung upon the shaft U, upon one end of whichis loosely journaled a chain-wheel, V, provided with a suitable friction-clutch and connected bythed ri vechain W with the feed-roller B. 7

When it is desirable to raise a' section ot' the beater-bed into an operative position the clutch X of the chain-wheel T is thrown into position, and, as the wheel revolves, winds up the chain R, and thereby causes the lower end of the rod K to travel toward the rear of the machine and the upper end to rise up, and thereby elevate the beater-bed to its proper position. The friction-clutch X is then moved out of position by means of the lever-handle Y. Backward rotation of the chain-wheel T is pre vented by means of the pawl Z, which engages with the ratchet-teeth cut on the rim of the wheel.

When it is desired to lower a section of the beater-bed the pawl Z is released from contact with the ratchet-teeth, and the beater-bed will shaft U is caused to revolve, and'the frictionbe carried down by its own weight and the 6o. videanumber of pulleys, F,looscly journaled chain R will be unwound from its wheel T. The beater-bed will then assume a nearly vertical position and will be out of the way or path traveled by the beaters,and unnecessary wear and tear will be avoided.

The beater-bed is composed of a series of ropes, A, one end of which passes over the rod B, that connects andbraces the outer ends of the guide-tongues D, and is bolted down to the cross-timber E. The other ends of the ropes pass over the grooved pulleys M, and have a weight, 0, attached to the lower end, which serves to keep it taut and in place within the groove of the pulley M.

To the bed-ropes A, I boltthe pads D, which consist of a rectangular frame of wood properly stayed and bolted. The two opposite sides or the ends of this frame are made higher or thicker than the side pieces, and over these is stretched the leather strip E, andthe whole is securely held in position by the bolts E, which pass through the leather strip E, the bed-ropes A, and the frame of the pad, as clearly shown in Figs. 4 and 5. Long leather flaps G are attached to the rods 11, which pass through and connect the metallic tongues or guides D D. These flaps overlap the pads D and ropes A and, extending over the rollers M,hang down toward the floor.

The carpet I is fed to the machine and over the rollers A B, and is prevented from falling between the rollers A and B, and from being drawn down and wound upon the roller 13, by the curved metal guide bars or tongues D, hereinbefore described. It then passes over the leather flaps Gof the beater-bed,andis then struck or acted upon by the heaters, after which it passes on and out of the machine.

The beater-shaft J is placed above and to the rear of the beater-bed, and is provided with a series of heaters, K, arranged in longitudinal rows, the beatersin one row corresponding with the spaces in the adjoining rows. The heaters K are composed of a length of rope bent into the form shown in Fig. 2, the outer or striking end being doubled into two flat loops, the starting or inner ends of each loop being firmly held together by the clampplates L and bolts M, as, shown in Figs. 2 and 3. Each inner end of the beateris placed between two metal boxes, N N, to which is attached the leather loop 0, by which the heaters are attached to their shaft in the usual manner. The inner surfaces-of these boxes N N are provided with transverse corrugations, and are tightly clamped upon the rope by the bolt and nut P, which also passes through and secures the loop 0 upon the boxes N, as seen in Fig. 3.

The feed-rollers are to he provided with the necessary gearing for driving the same, and also with means for reversing the direction of rotation.

The heaters are constructed of such alength that the strikingportion thereof will operate upon that portion of the carpet overlying the pads D, and thereby avoid,as much as possible, the sharp ridges formed by the ropes.

By this means fine carpets can be effectually cleaned by blows upon the back of the carpet without injury to the pile or face.

Having thus described my invention,what I claim, and desire to secure by Letters Patent, 1s-- 1. In a carpet-beating machine, the combination of the feed-rollers A B, endless belts or hands (J, adjustable beater-bed, and revolving beater-shaft J, provided with a series of looped heaters, K, all constructed, arranged, and operating substantially in the manner herein shown and set forth.

2. In a carpet-beating machine provided with reversible feed rollers, the adjustable hingedbeater-bed supported and operated by the rodsK K, mounted upon track-rollers, and held to place by the hinge-chain P and windchain R, pulley S, and chain and ratchet wheel T, operated and controlled by suitable frictionclutches andlever-pawls, and driven bya chain connection with the feed-rollers, substantially as and for the purpose shown and set'forth.

3. Ina carpet-beating machine, the beaterbed herein described, consisting of the ropes A, leathers G, and interposed pads D, said bed being permanently attached by one end to the frame of the machine, the outer ends being free and overhangingv the vertically-adjustable rollers M M, all constructed and arrangedtooperate substantially in the manner herein shown and set forth.

4. In a carpet-beating machine, the heaters K, formed of rope orsimilar material, and having the striking end bent to form flat loops, said loops being clamped together by plates L and bolts M, the whole being attached to the beater-shaft by the loop 0, and boxes N, clamped upon the ends of the heaters by the bolt P, substantially as set forth.

In testimony that I claim the foregoingI have hereunto set my hand and seal this .Mth day of November, 1882.
